Answer : An ionic bond is formed when <u>one atom transfers an electron to another atom.</u>
Ionic bond is formed when one or more electrons from the valence shell of an atom (electropositive metal ) are completely transferred to the valence shell of another atom (electronegative non-metal).
Ionic bonds form when one atom gives up one or more electrons to another atom. It is the complete transfer of valence electron(s) between oppositely charged atoms
For example NaCl (sodium chloride ) is an ionic bond, in which valence electron from Na gets completely transferred to the valence shell of Cl and ionic bond is formed between opposite ions that is Na (positive) and Cl (negative).
Note : Ionic bond is formed between metal (electropositive element) and non-metal(electronegative element).
Answer:
+3·F
Explanation:
The number of objects in the given system = 2 objects
The charge on each object are; q₁ = -Q, q₂ = -Q
The force acting between the objects = +F
The distance between the objects = 2·d
The formula for the force acting between two charged particles is given as follows;
Therefore, we get;
By tripling the charge, q₁, on the first object, we get;
q₂ = 3 × (-Q)
Therefore, the new force between them, F₂ = +3·F
Answer:
Light Exposure and Water Movement. Along with food, algae require the right amount of light to thrive. ... Filamentous algae will typically grow around the shoreline of a pond or lake because this is where the shallower water is.L
Hope that helps :)
Divide measured yield by calculated yield
140/176 = 79.55%
The atomic radius increases as you would go down a particular group on the periodic table of elements. This is because along with a greater number of protons, there would also be electrons as well, and thus the need of electron shells surrounding the atom would also be required, to compensate for the more electrons, as according to the bohr model, each shell contains 8 electrons in its electron shell. Thus the distance from the nucleus to the outermost shell increases, the atomic radius.
